ECE Colloquium: Helen Hong(Seoul Women’s University) “Medical Image Segmentation and Registration Techniques for Quantification, Treatment Planning and Surgery Simulation”

November 01, 2016 / 16:00 ~ 17:15

Speaker : Helen Hong

 

Abstract:

A Quantitative Imaging Biomarkers (QIB) is an objective characteristic derived from an in vivo image measured on a ratio or interval scale as indicators of normal biological processes, pathogenic processes or a response to a therapeutic intervention. The advantage of QIB’s over qualitative imaging biomarkers is that they are better suited to be used for follow-up of patients or in clinical trials.

In this talk I will introduce image segmentation and registration techniques, and their application for supporting quantification, treatment planning and surgery simulation. First, model-based segmentation techniques for extracting bone and soft tissues in CT and MR images are shown. Second, improved CV and graph-cut based segmentation techniques are introduced for solving several difficulties of original methods and for extracting lung tumors in chest CT images. Finally, rigid and non-rigid registration techniques are introduced for matching corresponding pulmonary nodules in follow-up CT images and analyzing lung motion in respiratory chest CT images.
